CHARLES E. WEI-IRENBERG, 0F BELLEVILLE,

ILLINOIS, ASSIGNOR T0 BELLEVILLE BALING-PBESS.

Application filed January 3,

T o all 'whom 'it may concern:

Be it known that I, CHARLES E. WE1-IREN- i-iniic, a citizen of theUnited States, residing at Belleville, Illinois, have invented a certainnew and useful Improvement in Baling-Presses, of which the following isa full, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same.

rIhis invention relates to baling presses, and particularly to balingpresses of the type shown in my prior Patent No. 918,620, dated AprilQ0, 1909.

One of the distinguishing characteristics of the baling press describedin my prior patent above referred to is that it has -a greater capacitythan balers in which division boards are used, owing to the fact thatthe feeding of the material does not have to be discontinued at certainintervals to enable the plunger to clear up the feed opening in thebaling chamber or compress the ragged end of the bale. In the pressshown in said prior patent the tie wires were first arranged in wireholders that extended transversely of the baling chamber, and at certainperiods in the cycle of operations of the press said wires were movedout of said holders and into the baling chamber in the path of movementof the plunger or compressing` device so as to arrange said wiresbetween the abutting ends of the two bales.

The baling press herein shown which conthe necessity of discontinuingthe feeding of the material at certain intervals, but .it differsslightly in construction from the press shown in my prior patent abovereferred to. The principal difference lies in the fact that the balerherein shown is so designed that the tie wires do not have to beinserted until after a bale has been completely formed. Anotherdifference is the elimination of the tncking device shown in my priorpatent above ieferred to without reducing the efficiency of the press orthe superior quality of the bales produced therein. There are alsoseveral other differences in the details point out.

mately the line 2-2 of Fig. l; Fig. 3 is a vertical longitudinalsectional view taken through the baling chamber and the tying chamber;Fig. a is a perspective view of one of the wire guides or members whichpermit the tie wires to be inserted after a bale has been compressed;Fig. 5 is an enlarged detail view taken on approximately the line 5-5 ofFig. 1; and Fig. 6 is a vertical sectional view taken on the line 6-6 ofFig. 5.

Referring to the drawings which illustrate the preferred form of myinvention, A designates the baling chamber in which the plunger orcompressing device l operates, and 2 and 2@ designate transverselyextending slots or openings formed in the top and bottom walls,respectively, of the baling chamber for permitting wire guides to beintroduced into the baling chamber. These wire guides preferably consistof straight bars or members B and B, each of which is provided with apair of grooves 3 for receiving tie wires that are drawn around a baleafter it has been compressed. The tie wires, of course, are not arrangedin the wire guides B and B at the time that said guides are introducedinto the baling chamber but said tie wires are introduced into thegrooves 3 in said guides while the bales are traveling through the tyingchamber, the operator who stands on one side of the press forcing thewires through said guides, and the operator who stands at the oppositeside of the press connecting the ends of the tie wires together. Flangesor projections 4 and 4a are preferably arranged at the sides of theslots 2 and 2a in the top and bottom walls of the baling chamber so asto form housings in which the wire guides B and B can be arrangedpreparatory to introducing said guides into the baling chamber, the endsof said housings being open so that the wire guides can be slipped intosame endwise. The upper wire guide B is moved downwardly into the balingchamber by means of a pair of arms 5 that are connected to a rock shaft6, and the lower wire guide B is moved upwardly into the baling chamberby means of a pair of arms 5a which are connected to a rock shaft 6a,said wire guides being long enough so that they will project slightlybeyond the ends of the housings in which they are arranged and 1 thuslie in the path of movement of the arms one end of said pitman so as tomove the 5 and 5a when said arms are moved inwardly or toward eachother. The arms 5zl form a support for the lower wire guide E when it isarranged between the flanges 4ta, and a. yielding plate 7 that normallycloses the slots 2 in the top wall of the baling chamber forms a supportfor the upper wire guide B when itis arranged between the flanges #ithat constitute the housing for said upper wire guide, said plate beingso constructed that it will yield inwardly and thus permit the upperwire guide to pass into the baling chamber.

The mechanism for actuating the arms 5 and 5 which position the wireguides, consists of a reciprocating pitman 8 that is connected to a pairof links 9 which are secured to arms 10 and 10l on the rock shafts 6 and6a, respectively, said pitman being moved in one direction by a crankarm 11 that revolves continuously while the press is in operation, andin the opposite direction by means of a coiled contractile spring 12.The end of the pitman to which the links 9 are connected, is bifurcatedso as to form jaws 13 which embrace a roller 1e' that travels between apair of channel-shaped tracks 15 secured to one of the sidewalls of thebaling chamber, as shown in Figs. 1 and 5, and the opposite end of saidpitman is provided with a head 16 that is adapted to be engaged by aroller 11a on the crank arm 11 when said pitman is arranged in a certainposition. The pitman 8 normally occupies such a position that the head16 thereon lies out of the path of movement of the roller on the crankarm 11 but means is provided for raising head thereon into position tobe engaged by the roller on the crank arm. The means herein shown forraising the pitman or moving it into operative position consists of alever 17 having. one of its ends arranged under the pitman so that whenits opposite end is depressed the pitman will be raised into theposition shown in broken lines in Fig. 1. After the pitman has beenmoved into this position the crank arm 11 will engage it and move it inthe direction indicated by the arrow ra in F ig. 1, thereby causing thearms 5 and 5L to engage the wire guides with which they cooperate andmove said guides into the baling' chamber in the path of movement of theplunger.

Owing to the fact that the lower wire guide B rests upon or is supportedby the arms 5a, it is necessary for said arms to rel main in theirelevated position for a short;l period after the lower wire guide Bhas;l been forced into the baling chamber, and I l have thereforeprovided means for locking the pitman when it reaches the end of its!stroke in one direction; namely, after it has l been actuated by thecrank arm 11. Said y,

connected to the side wall of the baling chamber and arranged in such aposition that one end of saine will drop downwardly and automaticallyengage a projection on the pitman after the wire guides have been movedinto the baling chamber. The projection on the pitman with which thelocking dog 18 coperates, can be formed in various ways but I prefer theconstruction herein shown wherein the pin 19 that connects the links 9and roller 14 to the pitman is provided with a head 12VL that forms a.stop with which the locking dog 18 cooperates. The weight of the lockingdog causes it to drop downwardly into the position shown in broken linesin Fig. 6 and thus engage the head 19a of the pin on the pitman, andwhen it is desired to release the pitman said dog is moved upwardly orback to its normal position, the dog being provided with a handle 18a sothat it can be operated conveniently.

rhe tying chamber, through which the bales travel after leaving thebaling chamber, preferably consists of a pair of channelshaped members20 arranged with their vertical legs or lianges projecting inwardly ortoward each other, and side plates 21 arranged between saidchannel-shaped members and spaced away from the legs or flanges thereofso as to form longitudinally extending slots through which the wireguides B and B project, as shown clearly in Fig. 1. These channel-shapedmembers and side plates are secured to the side walls of the balingchamber A by means of splice plates C, each of which is provided withvertical slots 22 that aline with the openings in the top and bottomwalls of the baling chamber and also outwardly projecting pockets 23that communicate with the slots 22 and with the longitudinally extendingslots in the sides of the tying chamber. The outwardly projectingpockets 23 that are formed on said tie plates provide a suiiicientclearance for the projecting ends of the upper and lower wire guideswithout weakening or reducing the strength of the tie plates.

The wire holders are inserted in the housings formed by the flanges L1and 4a, and after the plunger 1 has compressed a sulicient quantity ofmaterial to form a bale the lever 17 is operated so as to arrange thepitman 8 in operative position. The crank 11 thereafter engages saidpitman and moves it in the direction indicated by the arrow in Fig. 1,thus causing the arms 5 and 5a to move the wire holders into the balingchamber. The dog 18 drops automatically and thus locks the pitman andthe arms 5 and 5a in the position to which they have been moved. lVhenthe upper wire guide B moves downwardly it will engage the raggedmaterial at the upper rear end of the bale locking means consists of adog 18 pivotally l and wipe it smoothly down over the rear end 130 ofthe bale in practically the same manner as a tuclring device, said upperwire guide also operating to confine the ragged material or clamp itsecurely against the end of the bale. rlhe wire guides are now arrangedin operative position at one end of a bale, and as the press continuesin operation said wire guides will travel longitudinally through thetying chamber with the bales, each wire guide being arranged between theabutting ends of two bales. While the bales are traveling through thetying chamber the operator who stands on one side of the press, insertsthe tie wires through the grooves 3 in the wire guides, and the operatorwho stands at the opposite side of the press, ties the ends of saidwires together. After the wire guides have entered the pockets :23 inthe side walls of the tying chamber the operator lifts the locking pawl18 so as to release the pitman 8 and permit the spring 12 to return saidpitman and the positioning arms 5 and 5a to normal position, the weightof the pitman causing it to drop downwardly far enough to hold the head16 thereon out of the path of the rotating cranlr arm 11, and the headof the pin 19 cooperating with a stop 24 to limit the movement of thepitman in this direction.

From the foregoing it will be seen that a baling press of the characterabove described has a greater capacity than balers which employ divisionboards because the plunger does not have to makeA a numb-er of idlestrokes to-clear up the feed opening or comress the material at the endof the bales suiiiciently to permit the division board to be inserted inthe baling chamber.

l/Vith a'baler of the construction above described every movement of theplunger compresses a charge of material, and the downward movement ofthe upper wire guide wipes down the ragged material at the upper rearcorner of the bale so as to form a neat corner on the bale, said upperwire guide thus performing practically the same function as a tuckingdevice. The mechanism for actuating the arms which position the wireguides is of novel construction, and the tying chamber and the means forconnecting same to the baling chamber is also of novel construction.
